Cheap Radio Shack Chinese made detector. Worked fine and I had lots of fun starting out in the hobby with it. My son is now interested so I got it out of the garage where it has been for a few years and slapped new batteries in.

All I get is a constant high tone, even in battery test mode. Nothing I can do stops the tone. Even if I unplug the coils it makes no difference.

Any ideas?
 
ooh, interesting! No idea how to that though! Any "standard" ways that is done? Holding down Tune button while powering up or something?
